Thaing a frozen block

Any tips for thawing a Caddy 400 that was left full of WATER (suspect a shop) in a week of below 0 F temps? If I can thaw it I can have the car, since they think it's junk now anyway (assuming a cracked block)...

With only water in the block and a week at those temps the block is cracked...almost 100% guaranteed.

First thing to do would be to remove the belts that drive the water pump. If that area is packed with ice the water pump won't turn and the belts will burn.

I'd probably remove the rad hoses and use a heat gun or hair dryer tp thaw the ice out of that first. Chances are good the rad is cracked too though.

Then I'd fire it up and let it run for a few minutes...maybe 5-10 minutes. Shut it off and see if there is any water dripping or running out of the lower hose part of the water pump. Let it sit for a few minutes and then let it run a little more.

Once it's thawed, hook the belts back up, hook up the hoses again and fill with water and anti-freeze and see if it holds pressure. Check the oil, depending on where or if it cracked coolant might get into the oil turning it into a milky baby poop.
